CAN BE INSTALLED IN MULTIPLE UNITS- For Higher Capacity Requirements

PLUS A NEW FEATURE ! -
Flue Collector and chamber base assembly are built of aluminized or galvanized steel for
added life and protection against atmospheric corrosion.

The Thermotron OS Series is ideal for any application, residential or
commercial . The Thermotron OS Outdoor Boiler is preassembled for simple and proper
installation. Access to burner controls for maintenance and adjustments is easy but not
quite "child's play". Model OS Series is supplied with a 3450 rpm flame
retention, forced draft burner with a fast acting fuel pump for smooth, clean starts and
stops. In addition to hydronic heating, provision can be made for indoor tankless water
heating or mated to an indirect water heater.

In the rugged and dependable Thermotron OS Series of Outdoor Boilers,
Thermo-Dynamics has turned hydronic heating outside-in. We've taken the bulky, noisy,
exhaust-producing parts of the heating system and placed them outside. By doing this, we
have eliminated all need for chimney connections, making dependable hot water available
where it's never been possible before. And since it does not require an indoor chimney,
heat does not escape through this passage.

The performance dependability of the THERMOTRON OS Series is the result
of years of testing and field trials. Special steel flue restrictors are incorporated to
assure quiet, efficient operation. Durable heat exchanger constructed according to ASME
code using appropriate heavy gauge steel boiler tubes and boiler plate. Precase refractory
combustion chamber surrounded by insulating pellets for minimum heat loss through base.
